I feel as if most of what you wrote is professional common courtesy but more importantly and rightfully, filled with several exact approaches that would work well with almost every industry. I just stumbled across your blog from June 9th, 2016 this morning, while searching for cold email methods and believe these steps are true reminders of how, with great approach preparedness, will in turn cause great progression. This, I believe, will allow for a more successful and pleasing “climb up the ladder” in one’s career. The tips are words of wisdom that will definitely stand the test of time!
Obviously, it takes more work to create and place guest posts, but it’s worth it if the publication is aligned and authoritative. We found a way to create additional value with this as well by working with internal HubSpot experts who wanted to get their thoughts out on a given subject. For example, here’s a guest post that Blake Toder wrote for the Usabilla blog:
One of the most important compatibility factors to consider with email is the mobility question. How often do your employees need to access email via mobile devices? That's an important issue because most email hosting providers deliver some kind of web client usable as a default inbox. Almost all of these can be accessed via a mobile device, so if your employees don't need to access their emails on the road that much, then such mediocre clients are probably fine.
I want to say that I need to tread lightly here, though: nothing bothers me more than critique with no knowledge of internal data or skin in the game. After all, “It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena.”
Hi Bernie, actually time plays 3rd priority position to how you get customers to open your email. #1 is the message - what are you saying to get them to open the email?- on the subject line. #2 is making sure the content gives your customer information and opportunities that engage them into action. #3 is the day or time of day. Then as some have mentioned.. TEST! Be prepared to try different messages and times to see what resonates with your audience. Make sure to choose a service... 

The first autoresponders were created within mail transfer agents that found they could not deliver an e-mail to a given address. These create bounce messages such as "your e-mail could not be delivered because..." type responses. Today's autoresponders need to be careful to not generate e-mail backscatter, which can result in the autoresponses being considered E-mail spam.
ProtonMail was founded in 2013 by scientists who met at CERN and were drawn together by a shared vision of a more secure and private Internet. Since then, ProtonMail has evolved into a global effort to protect civil liberties and build a more secure Internet, with team members also hailing from Caltech, Harvard, ETH Zurich and many other research institutions.
ProtonMail is a basic email service that is easy to set up because it doesn’t ask for any personal information. You just pick a user name and password, and you’re set. Be aware that some features – such as mail collection and the ability to sync across multiple devices – are only available with its paid email service. But the free version does have email encryption, which is important if you send messages with sensitive information you want to protect. ProtonMail automatically unencrypts the message when it reaches the recipient’s inbox and is opened.
You can attach files up to 25MB and upload more than one at a time. Once they are attached, documents and images are displayed as thumbnails, so it’s easy to verify you’ve attached the correct files. When you receive attachments in an incoming message, these, too, are displayed as thumbnails so you can preview and sure they are safe to download to your computer.
But your service provider isn't your only worry. If you've opted for any third-party email integration, like combining your email with a third-party customer relationship management (CRM) provider (such as Salesforce), that opens your company's email up to either data-snooping apps deployed by Salesforce or to any data breaches that originate with that service. So the more informed you can be about what's attached to your email service, how that data's being used and accessed and especially by whom, the better off you'll be when it comes time to send confidential email.

Analytics and reporting: Once you send an email, you'll want to determine how it's doing. Most services provide a range of data, including how many emails you sent, how many of them landed in inboxes, the bounce rate, who opened your emails, and the number of clicks and opens by location. Click-through rate and open rate are two basic metrics all email marketing services should provide. Those are important metrics to track for businesses.

Hi Lexi! Email marketing metrics can differ based on industry. Often times email marketing can be another way to stay in touch with customer and remind them of your great service. I would evaluate your current emails and see if there is too much content in a monthly newsletter. Are people clicking? Are they even opening? Sometimes increasing emails to two a month with one featuring an employee or client testimonial which the other gives customers an offer such as a discount can increase...
I would like to read more of what you might have at the ready (all blogged subjects) that you might deem to be useful for me; for I will read all. And if you possibly had any insightful tips on ANYTHING that you might see as helpful, please reach out to me most graciously, or send me to where I should search. (Sorry, sounds like I am “breaking” one of the 11 tips, by “taking more than giving”)
We tried to give as much value as possible in these emails without being spammy or annoying. We also tried to keep in mind that all of this influencer outreach was not only about the short-term benefit of acquiring links, but it also served the purpose to stake out a place in the customer success space and build relationships with important, smart people.
While social media is an important part of marketing strategies, email marketing remains a vital method to reach your audience. When you use email marketing services, you can post sign-up forms on your social media platforms to grow your contact list. You can also schedule posts on your social media platforms and track your followers' engagement to determine what's popular. 
Robly's OpenGen technology utilizes a traditional email campaign process; however, OpenGen then resends your campaign one to 10 days later, with a different subject line to those subscribers who didn't open the first campaign. The system sends emails one at a time, at the moment subscribers are most likely to check their inboxes. The service features A/B testing, a pop-up widget to increase contacts and mobile-responsive templates.
